I can relate fully with you. Last year, at age 64, my wife scheduled my first visit, with a heart doctor. Although, I had never thought of having heart problems. I have gone to the gym religiously for over 30 years. The CT scan revealed that I also have an ascending aneurysm, the same size as yours. My initial heart doctor instructed me to not lift anything over 10 pounds! I was terrified, & thought I was at death’s door. After a couple of visits, I decided to get a second opinion. My current heart doctor advised me to continue going to the gym with no weight restrictions, other than not to be lifting anything excessive. I have lifted weights, on average, three times a week, for the past year. I just completed my annual CT scan, and I’m happy to say that my aneurysm is still at a 4.1. I hope that you can too, can get over the initial stress of having an aneurysm, and have a great life. 😊
